Answer:
tension in rope = 25.0 N
Explanation:
Two forces act on the suspended weight. The force coming down is the gravitational force and the upward force by the tension in the rope. Since the suspended weight is not accelerating so that the net force will be zero. Therefore the tension in the rope should be 25 N. ∑F = F - W = 0
so
F = W
so tension in rope = F = T = 25 N
Answer:
7.5 miles
Explanation:
0.25 hours=15minutes.
So you do
30 miles=60minutes
x =15minutes
cross multiply
Ans-7.5
